Large updates to the documentation.

MemArena is updated to support temporary allocation, along with documentation on how to use that functionality.

Some minor bug fixes, support for As_Hex in BufferWriter.

Documetation and regularization update.

This update is primarily a documentation update, with a focus on TextView and BufferWriter.

There are also some updates to the BufferWriter formatter API for better handling of custom formatting.

MemSpan Update

This updates MemSpan to be template based.
